I am fascinated by these "impedance at 60 Hertz"-type capacitor ratings. This is not the first one that has been discussed here or on the Antique Radio Forums. Do any of you have a good explanation of why these were specified, and rated, that way? They are always very-low-voltage capacitors, too, it seems. My only guess is that anything above about 500 microfarads was considered so odd or rare (or even almost unmeasurable directly at that time), that they did not even try to mark them in terms of capacitance but rather used this type of AC measurement as a more repeatable indicator of value.
